PROBLEM TO BE SOLVED: To prevent grain culms and waste straws from being wound to a winding-prevention cylindrical body covering a rotation shaft of a raking-in star wheel.SOLUTION: A reaped grain culm raking-in device includes: a right/left raking-in device 3 including a raking-in rotation body 5 raking in grain culms planted in a field; and a winding-prevention plate 9 arranged on a rear side of a winding-prevention cylindrical body 8 covering a rotation shaft 7 of the raking-in rotation body 5 and preventing winding of grain culms to the winding-prevention cylindrical body 8 in the proximity of a peripheral part of the winding-prevention cylindrical body 8. The winding-prevention plate 9 is arranged at a position in the proximity of an upper face of the raking-in rotation body 5. A rear end of the winding-prevention plate 9 extends to a rear position with respect to a peripheral track of the raking-in rotation body 5. A raking-in conveyance chain 4R is on a rear side of the raking-in rotation body 5. The winding-prevention plate 9 has a face in a vertical direction and is arranged generally in parallel to the raking-in conveyance chain 4R in plan view.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】掻込スターホイルの回転軸を覆う巻付防止筒体への穀稈やワラ屑の巻き付きを防止する。【解決手段】圃場に植立する穀稈を掻込む掻込回転体(5)を有した左右の掻込装置(3)と、掻込回転体(5)の回転軸(7)を覆う巻付防止筒体(8)の後側に配置され、巻付防止筒体(8)の外周部に近接して巻付防止筒体(8)への穀稈の巻き付を防止する巻付防止プレート(9)とを備える。また、巻付防止プレート(9)は、掻込回転体(5)の上面に近接する位置に配置される。また、巻付防止プレート(9)の後端部を掻込回転体(5)の外周軌跡よりも後方の位置まで延設する。また、掻込回転体(5)の後側に掻込搬送チェン(4R)を有し、巻付防止プレート(9)は、上下方向の面を有すると共に、平面視で掻込搬送チェン(4R)と略平行に配置する。【選択図】図2
